To all whom it ma concern:

Be it known tin, ,Hnmmm LIFE R ch, a citizen of-the ited States, residing at Mount Pulaski, in the county, of Logan,

State of Illinois, have'invented a ,new .sind

useful Lock-Washer for Nuts and Bolts; and I do hereby declare'the following tobe a full, clear, and exact description of thc invention, such as will enubleothers skilled in the art to which it appertains to mnke and use the Same.

This invention relates to th art of nut locks, and more especially un improved, simple, and efficient .lockingwusher for bolts and nuts particulgrly nuts.

One of the objects of the invention is to provide a device of this kind, in which simple, efficient andpractical features of construction exist.

One of the features of construction is to provide a dishedwvasher, which is substantially rectangular inelevatlon, and is provided with a plurality of veshaped slits extending from the central opening of the washer, so that when a nut isthreeded home on abolt, the locking washer will to? crushed, particularlythe ports of thewesher between the slits, thereby eausingteethupon the inner edges ofthosetparts to-bite nto the threads of the bolt, thereby preventing dis lacement of the washer.

nother feature of the invention is the provision of a washer of. such size that after the Parts. between. the slits are crushed, the portion of the. washer beyond the outer ends of the/slits may be soi-nrranged against. the nut as to preventntheonut irornbacking 0 -'tionmay: newssitute el teretions, falling within the scope oftwhet, 1s The ntion eomprises v urt er ,ffPliillQ:

A suitablenut .is first threaded Up'on'the bolt adjacent to one of the fish plates, and between tli'ehut 4 and a larger nut '5 (which is subseqiiently appl ed tothe bolt (is a 'wesher 6 recdt'rigular in plan view, ut, however, lt' nti'f'fbe constructedin any other suitable shim/pet fBeferrmg more'especigtlly to 4 and 6, it is to be noted. that, the washer is dished, and extending radially from the 0 ening"? of the washer are several V-shape slits 8, and the parts 9 between'the slits are provided with teeth 10, upon their inner edges." It is contour or'shape 'of'the Washer is crushed between theftwo nuts 4 and 5. In otherwords, the arts 9 are crushed flsit between the two nu s, thereby closing the V-shd'ed slits 8, and cousin the inner toothed of the )artsS to bite into the threads offt e bolt, tiereby preventing movenientofthe washer.

Thewusher 6 is provided with an elongated laterallyextending tongue 6, which, afterthewa sheris crus'hed, may be bent overfthe nut 5, thereby preventing movement of the nut. However, it is to 'n'oted that, the wa' 'sher is larger than the ni'i'tli,that is, in plan, view; *In 'other words, theinut is substantially its wide as the distiince iro n the oute'r end of one slit "8 "to'the outer ,end of an opposite or adjacent slit.

of the screw, the outer portioiis' or the washer will overlie the nut 5, as shown at 11, thereby tending to revent the mitt" from unscrewing, In act to insure the urity i the nut 5,"the parts 1111321? be 1 orced toward the nut that .iafli'tmbsolutely n contact with Woo inc, n t; utm rel 6 direct on ofthe onut,to prevent; to same from turning.

right and left threiids, 'as' shown ind i' 1 and 2, -it is to bosom that the teeth 10. one part 9 will engage, say" for the right hand threalls, unll the teeth ll) of the opposite part will engage the le'l't hum] threads, or vice versa. l'lowever, lll l lg.

3 .the left hand thremls f thejhnlt are eliminated, tli er el'ij leaving only the right hand threads, and where the washer is pm vided with a tongue as shown at W; it-is only necessary to have one nut.
